So I bought the pace model.
Did an interval workout on the treadmill, after I checked the app it measured 195 heartbeats/second. Which was nice and well becase i know thats where I end up at the end of those 4 minutes.
However, after that I did some strength training, and then finished off with some uphill walk on the treadmill where the treadmill measued 150 BPS, and my watch... 88 BPS. I know 150 is more accurate because my breath was around there.
After that, it hasnt been able to register anything over 110 BPS. Tried it for several workout sessions, still doesnt measure above 110. I tried factory reset.. doesnt change anything.
Someone else seen this?
I'm testing one amazfit and comparing with one garmin 630.
Amazfit measures correct just after 10 minutes of workout and then, after some minutes it measures wrong about a minute or two, and back to measure correct again.
Very bad algorithm.
Has nothing to do with bad algorithm.
Why do you guys think that there is no gym workout on the watch?
Because there is no known wrist hr sensor that is working correct for that.
Doing workouts means bending and flexing the wrist, which means that the sensor looses contact, which means inaccuracy .
And 90% of people that complain, have the sensor on a spot that is not really working.
Have seen very hairy guys complaining or people that have the watch "between the hand and the bone".
And make sure it is tight.

Holy crap, 195 beats PER SECOND!!?!! How are you still alive? Are you The Flash? Or possibly some kind of super smart hummingbird with an xda account (that would be cool).
Jokes aside, I also find the HRM on the Pace problematic.
It seems to work ok when you do "check now" as long as you stay still and its on tight. But whenever I use continuous HRM or do an activity like biking the reading seems to be about 20+ bps too high.
For example, I did "check now" just before a bike ride and got 65bpm, then again right after the ride and got 104bpm, but the bike activity recorded a starting heart rate of 84bpm and an ending rate of 134bpm.
yeah, sometimes my watch seems to measure my heart rate correctly, but other times it shows quite strange results.
I just finished indoor cycling workout. I used together Suunto Ambit watch with HR strap and Amazfit Pace. Amazfit HR data is useless. Here is merged image with both graphs.
Amazfit was tight, and my hand didn't moved to much. I tried several times to move hand on different positions to check is there any improvement, but without change.
Here is paralel graph (top is Suunto, bottom is Amazfit)
sometimes when physical exertion increases (when I go up a slope, for example) the heart beats are reduced.
The HR sensor in the pace seems about as accurate as someone guessing your heart rate from across the room.
Yes the bip is the same.
Absolute ****.
I've compared it with Polar watch + chest strap. There were differencies in the meassured pulse, however the average pulse for the trainings was very close on both devices. What is important for Peace, it has to be fastened very tightly on the wrist.

I have compared Amazit Pace (1.3.6d) with Garmin Chest Strap HR monitor and FR235 doing Interval training running, and to FR235 optical HR monitior doing indoor biking.
In both activities Amazit Pace worked inestable the first 10 min then worked showing nearly same HR thank Strap HR and optical HR monitors.
Amazfit Pace showed a sudden decrease in HR reading about the middle of activities (about 1 hour each) and then back to proper reading.
In summary, Amazfit Pace uses about 10 min to have proper HR values, and sometimes during the activity has sudden decreases in HR reading.
For the rest of activity it performs quite well.
but you know that you can pair amazfit with a heart rate monitor strap, for example Polar H7?
This is about the Pace, and that can't be paired with a strap.

oh, ok, i was talking about Stratos
heart rate sensor go crazy
I have the pace model too
sometimes (recently with more frequency) the heart rate sensor go crazy
yesterday, when i did an Indoor Run, he show the alert: "heart rate too low: 75", seconds after this, he show: "heart rate too high: 185", seconds after: "heart rate too low: 81", "heart rate too high: 172", etc etc.

Is the watch brand new? Do you sweat a lot? Check the cover of the HR sensor, some people that had used the watch while bathing/showering had problem with the cover getting loose.

I bought my pace in Feb/18 (3 months ago)
my sweat is near to zero
never bath/shower using it
the pace work well until one week ago, when i need to do a factory reset because something was draining the battery too fast (one charge in one night)
after the reset, the battery issue has gone, and the watch work well until yesterday (when the HR sensor issue start)
thinking about do one more factory reset... :fingers-crossed:
just to illustrate: HR (red) x Cadence (blue)

Same issue here, with every Rom update HR accuracy gets worse in Sports activities. Continuous HR monitor seems accurate when compared to my chest strap, but goes haywire and at least 50% off true when in Run Indoor and Cycle indoor. Elliptical seems to be accurate at least some of the time. Have factory reset many times but nothing seems to help.
Yesterday I realized that with new ROM update, Peace have option to connect to other Bluetooth sensor(s).
I tested it and it with cheap 20$ Bluetooth sensor and works nice.
Hello, i own an amazfit bip since afew weeks, and i am disappointed by the GPS accuracy. I can see drifts on my way, and the total distance is always wrong.
I am running in a city, so i beg it is a part of the reason.
Having a look at the GPS files, it seems that the watch only records the position once every 20 seconds. The frequency is really poor, is it normal? The GPS cannot be accurate knowing that...
Thanks
Hmmm, this doesn't seem normal. Pace records every 1-2s, and also records the accuracy in the internal database when doing it. The compass works fine on watch? Maybe someone else with a BIP can give more info...
I also have a BIP and the distance is totally wrong.
Actually the distance by step counter is more accurate than BIP GPS.
Also it seems to increase distance while standing still.
roughly 100 meters every 5 minutes.
And all that with perfectly clear sky.
I have a bip and I think it's accurate. I did compare with my arrival SQ-100 and no difference at all. In middle of city doing 20km and at the end the diference was only 10-50 meters.

When did you buy yours?
I bought mine 1 week ago and have the last FW: v.1.1.2.05
The barometer on my Pace is stuck at the same reading. I have tried gently blowing in the hole, cleaning it etc. I also tried a factory reset.
But the altitude is changing. So is altitude determined by GPS or the Barometer ?
Hi
The elevation is measure using the barometer and not by GPS.
Seems your barometer faulty that not reading any elevation. Same time, did your battery life span normal as it in stanby mode (leaving untouch on table) using 10% over 24 hours (plus minus)?
Did you wear it during shower or swimming. Thia watch is only resistance to water splash in small quantities.
Probably you could explain the last successful of elevation reading and then become faulty of the activities you did.

I am aware of this fault & my battery seems fine. I have never got the watch wet & it's only a few weeks old .
The barometer is permanently at 1024 but the altitude does change.

For some activities you can enable the data fields: altitude gain and altitude drop, may help.

Thanks. There is an app that puts pressure changes on a graph but it's continuous so collect huge amounts of data. I would of thought that the dev could easily add interval measuring.
It's a waste to have a barometer that has a limited use. It could be like the barometer on a Suunto watch.

I bought a Stratos to replace my amazfit bip and playing soccer, my stratos show around 185 bpm. It's impossible such reading. My old bip never showed more than 150 bpm (using treadmill as activity).
Is this sensor so bad? Can be improved in future updates?
As test I compared it to my fitbit and garmin and al readings are quite the same in workout and rest/sleep.
If I have a sprint or Hiit training my heart rate can spike to 190bpm. So 185 is possible depending on your workout.
Make sure your watch has the latest firmware, reset its data (factory reset then do not restore old data when pairing again) and use continuous HR for at least 24h and it should works a little better. Unfortunately the PPG sensor used in both Pace and Stratos isn't the best one around...
Hi Vogal , I'm experiencing the same as you.
I had a Bip for a year and a half. In the beginning HR was always 20 beats too low. If I wore in on the inside of my wrist, it was almost perfect.
I recieved my Stratos yesterday, it updated itself 3 times, even to the latest 2.3.8 that was released yesterday. I unpaired, rebooted, repaired, but didn't factory reset. HR is ALSO 20-30 beats to high. When standing still, measurement is perfect. But when moving, it's awful. On both watches.
Did you do a factory reset? Did it help?
My stratos HR works fine in spinning and elliptical machine. I compared it with another hr monitor with chest strap and both show very similar values. The problem is in outdoor activity like MTB. Here the stratos seems not realize about peaks of exercise and It always shows moderate values below 150 when the chest strap gives me values over 165. I tried tighting it more and different positions on my wrist but without any read improvement.
People, Pace/Stratos/Verge use a PPG sensor, it will never be accurate if you move your wrist/arm a lot, it is specially true when riding a bike... If HR accuracy is needed, use an external HR band.
The problem isnt the Stratos

The problem isnt the Stratos, its de Bip. I had one and never gave me the same value of the HR mesure of the running machine, also I tried with an Apple watch in other wirst and both, the running machine (also the eliptical) and the apple show me the same HR but the Bip was allways 30-40 beats lower
Hi,
I have a Stratos 3 and was expecting a better GPS Accuracy.
Have recently updated it to 4.2.2.1 and it improved but it still takes take some time to lock signal.
Also, after a few experiences, I have noticed that if you start the activity immediately after locking signal the first few minutes will be inaccurate and it is better to wait a few minutes.
Any experiences from anyone else?
What pair are you using?

Same here - I had the first Stratos and finding GPS signal was quite a bit faster than on the new one. Hope they'll do something to improve it. Though, considering what have they done with the Amazfit app, I'm not very optimistic...

I have tried GPS + GLONASS and GPS + Galileu so far.
Galileu was accurate after the first 5 minutes only.
i'm expecting the same with my Stratos 3: GPS+ Galileo if start activity immediatly after GPS Fix it needs some minutes more to be accruate (5 min) but after it's perfect (i'm cycling in forest)
I did not try GPS+GLONASS for the moment will do it next time to see if it's better for initial fix and if tracking accruacy is as good as GALILEO
Gps and heart sensor
Hi, I sold my gtr because gps didnt work, I thinking I a Stratos 3, What Is it The heart sensor accuracy?

the HR sensor is exactly the same so you know it!
Tks for reply... I think that we need to considering the sw factor as well....
Sad to hear that, I'm using a Pace and thought Stratos 3 as a improvement over GPS accuracy and Heart rate.
Pace is a mixed bag, sometimes it's very good but, even in open areas, sometimes the accuracy show my position on the other side of the street.
Often I experience inaccurate position on the first minutes also.
Let's hope for a software update to increase reliability.
Stratos 3 uses the new HR sensor used in both Verge and GTR/GTS, so it should behave the same. It's a bit bigger and should work better than the ones from Pace and the original Stratos, as it does if I compare my Verge with them. Just don't expect it to be perfect, as any other PPG (optical) sensor.
The same issue with Pace and Stratos (v1). You should always wait 2-5 minutes at the green Go screen before starting activity recording. Also, with Pace, I used to run with Airplane mode for better accuracy, but it looks like in current versions it makes no difference (better accuracy in both cases than early). That way you can avoid GPS inaccuracy. My Stratos 3 is on the way.
Are you on latest firmware? I had mine for a week and updated it the first day. GPS is very good and fixes fast (I returned the GTR because of the GPS being so bad). Maybe your issue could be location related? Like AGPS data related?
@Paxy
Weird. I'm a new Stratos 3 user.
I have no accuracy issue with the GPS (Glonass) and the fix is done in less than 30 sec. Unlike the GTR, I sent back whose GPS was a deep sh.t.
I made 8 cycle workout and it worked very well. I leave near Paris there is buildings (not too high) around me during my
sessions and the recorded track is very good.

Can you, please, post an example, I'm thinking on ditching the GTR and considering a Stratos 3(which should actually be 2, because the first one was called Pace)?

Hi here is 2 run one with GTR and one with Stratos, there is NO comparison.
In orange, the trace recorded by both watch and under you'll find the covered distance which totally approximate on the GTR as most of the run was not receorded.

Thanks for taking the time to post these.
Seems pretty accurate. Have you checked through google maps to see if the distance is accurate? Is this the route: https://www.google.ro/maps/dir/48.8...0x47e67b314410fbbb:0x21dd71e67173a3e0!1m0!3e1 ?
@winni21 That's how my GTR cuts corners as well. Stratos 3 seems very good.
Now I'm pretty sure the GTR has faulty hardware for GPS (frame used as shared antenna with bluetooth), since they both have the same gps chipset and will never get fixed through software update.

Compared to Google Maps, the given distance by the Stratos is pretty accurate as I have 9.53km for stratos and 9.6 for GMAPS.
But on my road I have to go in a tunnel for few meters and the GPS signal is lost at this time. On this section the Stratos show a straight line and google map a nice curve. The curve is around 200m, so this part explain partially the 70m missing on the Stratos.

You are wrong. There is the Pace and there is Stratos (in China called SportWatch 2). There is no Stratos2 and Pace is not Stratos1.
My Stratos3 just arrived. It has fast GPS fix, but haven't tested accuracy yet.
I will compare it's accuracy against Pace soon.
BTW. Huami declares only Pace, Stratos and Stratos3 as sport watches. GTR,GTS,Verge etc are just smart watches without GPS in the focus of development.
There is also Stratos+ on Amazfit official web. The problem with the naming comes from resellers giving different names like Startos 2S or Pace 2.
But indeed there are 3 generations of the Amazfit Sports watch (Pace, Stratos/Stratos+ and Startos 3)
